Application February 24, 1954, Serial No. 412,169

2 Claims. (Cl. 30-48) This invention relates to an improvement inrazors, and more particularly to a razor of the character shown anddescribed in my patents Nos. 2,094,827; 2,073,713 and 2,073,714. In saidpatents are shown razors, and blades therefor, in which the blade is soflexed that one of its cutting edges ascends and the other cutting edgedescends at the sameend of the razor, and by this particular inclinationof the cutting edges a desirable angular cutting effect is obtained.

In my Patent No. 2,073,714 is shown a razor of the above-mentioned typein which a blade is used provided with a central elongated slot havingan axis at an angle to the cutting edges of the blade. This razortherefore requires a special blade of the above construction,necessitating special machinery for its production. Also in the abovepatent, the razor, in order to accommodate blades of the constructionabove described, has its lugs or pins arranged at an angle to thelongitudinal axis of the razor head.

While razors of the character herein mentioned have been made and sold,efforts to so flex or bend the blade between the cap and head of therazor in a manner to provide inclined cutting edges have invariablyresulted in an arched or curved cutting edge, or an edge which is not incontinuous, even and straight-line contact with the teeth of the guardor so-called comb on the razor head. While this is not true of the razorand blade shown in my Patent No. 2,073,714, it is noted that thestructure of that patent requires a specially-constructed blade. Theuser of razors of the wafer-type blade are accustomed to being able tosecure replacement blades almost everywhere, and therefore any razorwhich attempts to utilize special blades usually does not meet withmarked success. On the other hand, a razor having the advantage ofproviding the desirable diagonal cutting edges has important advantagesand results in improved shaving. Hence it is an important object of thepresent invention to provide a razor having all of the advantages ofthat shown in my Patent No. 2,073,714 coupled with the ability to employwafer-type blades of standard construction and procurable throughout theworld.

With this and other objects to be hereinafter set forth in View, I havedevised the arrangement of parts to be described and more particularlypointed out in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of theinvention is disclosed,

Fig. 1 is a front elevation of a razor constructed in accordance withthe invention;

Fig. 2 is an end view of the same;

Fig. 3 is a top plan view of the blade table or guard, sometimesreferred to as the head of the razor;

Fig. 4 is a plan view of a standard type of wafer blade adapted for usein my improved razor;

Fig. 5 is an end view of the guard or head of the razor;

Fig. 6 shows how the blade is flexed when it is in place in the razor,and

Fig. 7 is an end view of the flexed blade.

The razor shown in the drawing is of the so-called hoe type, which, inits original form is credited to Gillette, and includes a handle 1 and aholder for a double-edged wafer type blade, said holder consisting of ablade table or guard 2 and the blade clamping element or cap 3. Adouble-edged wafer-type blade 4'of standard construction, is adapted tobe clamped between the guard 2 and cap 3 in such' position that the twoparallel cutting edges 5 and 6 of the blade 4 are brought over theserrated edge portions or comb parts 7 of the table or guard 2. Theblade 4 may be any one of standard form and one of the many similartypes now marketed. The blade includes a central elongated slot 8 havingits longitudinal axis extending parallel to the cutting edges 5 and 6 ofthe blade. This slot varies in shape in different types of blades, butin all standard blades it includes the enlarged holes or openings 9through which the usual studs or projections provided on the under sideof the cap 3 extend. These studs or projections pass through theopenings 9 in the blade and through complementary holes 10 pro-'- videdin the blade table or guard 2 and shown in Fig. 3. The central opening10 in the table 2 as well as the center opening 9 of the blade 4,usually permits of the passage of a threaded stud formed on theunderside of the cap, and which threads into a threaded bore in the topof the handle 1 to thus hold the handle, guard or table, blade and capin clamping relationship. The elements and features all above describedare of known construction and are set forth herein primarily for thepurpose of indicating their relationship to the novel features of thepresent invention, which features will now be described.

The upper surface of the blade table or guard 2 has a central area 13located between the imaginary parallel lines 11 and 12, which area istransversely curved to conform to conform to the surface shape of acylinder. Disposed on either side of this cylindrically-curved surface13 are two substantially flat, inclined surfaces lying on either side ofthe cylindrically-curved area 13 and extending from the edges of thecylindrically-curved surfaces to the serrated edges of the table orguard. These two flat surfaces 14 may be substantially triangular inoutline. The transition of curvature from the central cylindricalportion 13 into the flattened triangular surfaces 14 is gradual so thatthe blade is easily curved to conform to these surfaces 13 and 14 whenit is clampingly positioned between the guard or table 2 and the cap 3.It will be understood that the under surface 16 of the cap 3 relativelyclosely conforms to the upper surface of the table or guard. That is tosay, the under surface of the cap is formed with the central cylindricalsurface corresponding to that at 13 on the guard bortiered by theflattened triangular surfaces corresponding to those at 14 in the guard.

When the blade 4 is placed in the razor between the table and cap, theblade will be flexed about a line indicated substantially at .i5l5 inFig. 4 and thus will be flexed centrally or axially of the cylindricalarea 23. it will be observed that this line of flexure is at an angle tothe cutting edges 5 and 6 of the blade as well as being at an angle tothe longitudinal axis of the slot 8. The cutting edges 4 and 5 willassume the angular positions shown in Fig. 6 with one cutting edgeraised and the opposite cutting edge lowered at the same end of therazor. Because of the fact that the portions of the blade locatedadjacent to the cutting edges are flattened, or they can be curved asthough shaped over the surface of a cone, the cutting edges 5 and 6 willbe straight and thus will be equally spaced from the serrated edges orso-called comb" portions of the guard or table 2 for the entire lengthof the comb.

As a result'of the above arrangement of the blade and facially-opposedsurfaces: on the cap and table; the cutting edges of the blade arediagonal and an effective, angular shaving stroke is attained. Animportant factor also resides in the disposition of these cutting edgesin straight-line contact. with the. comb portions and this-despite thedistortion of the blade from its. normal fiat formation to that shown inFig, 6.

Having described one embodiment of the invention, it is obvious that thesame is not to be restricted thereto, but is broad enough to cover allstructuresfceming withinthe scope of the annexed claims.
